Blockbench-Farm land block glitch

I think that a problem with your client not the game. Works fine this end.

The Java-version will not be updated anymore. The game works fine. I had always problems with the pnb-plugin, so I never used it for the server.

That's weird Which PNB plugin do you use exactly? Unfortunately I couldn't reproduce this issue on my end (at least with the latest PNB plugin)...

If this happens again, maybe you could post a report? To do that, open the console and type "report" - then a file called "report" should show up in the game directory. Please upload that file here (or send it via PM to me), maybe it contains more information about what's going on there

Yeah, that's indeed the latest PNB plugin... I couldn't reproduce the issue on my end unfortunately, but if you run into this issue again, please create a report file and upload it here
